Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg yolks until light.
Add the milk to the yolks and pour part of this mixture onto the flour; beat until light and smooth.
Add the remaining egg yolks, milk, salt, and melted butter; mix well.
Butter muffin pans and half fill them with the batter.
Bake and serve
Bake for 20 minutes at 400°F (200°C).
Serve on a hot platter with the sauce poured over them.
Make the sauce
For the sauce, beat the egg whites to a stiff froth.
Gradually beat in the powdered sugar and then the juice of the fruit.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enriches the batter and helps set the puffs as they bake.
- Egg whites
- Whipped into a foam that gives the sauce its light, airy body.
- Flour
- Provides structure so the puffs hold their shape after baking.
- Milk
- Adds moisture and liquid that turns to steam, helping the puffs rise.
- Butter
- Adds fat for richness and a tender crumb.
- Powdered sugar
- Sweetens the sauce and helps stabilize the whipped egg whites.
The step that matters
Whipping the egg whites to a stiff froth. Egg whites trap air when beaten, but any trace of yolk or grease prevents them from foaming fully. Adding sugar gradually helps the foam hold its shape and stay glossy instead of collapsing.

Fit is the average pairing score against egg, flour, butter, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
